The author and screenwriter of “Pride and Prejudice and Zombies” was to make his directorial debut with this massive DC Entertainment superhero film. Grahame-Smith wrote the script for the project, based on a treatment from Phil Lord and Christopher Miller. The studio will retain his original story but will have to look for a new director to take his place.

“The Flash” has a release date of March 16, 2018 – still a ways away to find a new helmer without making any changes to the day. The action film stars Ezra Miller as Barry Allen, who made his debut as the scarlet-speedster in “Batman v Superman: Dawn of Justice” and is currently filming “The Justice League Part One,” which will be released in 2017.

Grahame-Smith will continue to work with Warner Bros. and is a writer on “The Lego Batman Movie” and is working on the “Beetlejuice” sequel.

Over a year ago, the studio faced a similar situation when Michelle McLaren left the production of “Wonder Woman” over “creative differences” and was then replaced by Patty Jenkins. The Gal Gadot-led flick is set to open on June 2, 2017.
